The diagram given below is a vapour pressure-composition diagram for a binary solution of A and B.In the solution, A-B interactions are

A

similar to A-A and B-B interactions

B

greater than 1-A and B-B interactions

C

smaller than 1-A and B--B interactions

D

unpredictable.

Text Solution

Verified by Experts

The correct Answer is:
C
The given figure is showing positive deviation from Raoult.s law.
`P_A gt P_A^@ X_A`
Thus A - B attractive force should be weaker than A - A and B-B attractive forces.

The diagram given below represents boiling point composition diagram of solution of component A and B. Which is/are incorrect among the following ?

Answer the questions (given below) which are based on the following diagram: vapour pessure diagram for real solution of two liquids A and B that exhibit a negative deviation from Raoult's law. The vapour pressure of both A and B are less than predicted by Raoult's law. The dashed lines represent the plots for ideal solutions. Solution containing components A and B show this type of deviation from ideal behaviour when:

Vapour pressure diagram for real solutions of two liquids A and B that exhibit a positive deviation from Raoult's law. The vapour presssure of both A and B are greater than predicted by Raoult's law. The dashed lines represented the plots for ideal solutions. A : This is obserbed when A...B attractions are greater than average of A...B and B.....B attraction : B : DeltaH_(mix) = +ve, DeltaV_(mix) = +ve C : Boiling point is smaller than expected such that vaporisation is increased D : Mixture can from azeotropic mixture Select correct facts.

Answer the question (given below) which are based on the following diagra. Consider some facts about the above phase diagram : Vapour pressure diagram for real solutions of two liquids A and B that exhibit a positive deviation from Raoult's law. The vapour pressure of both A and B are greater than predicted by Raoult's law. The dashed lines lines represented the plots for ideal solutions. A : This is observed when A...B attraction are greater than average of A...B and B...B attraction: B : DeltaH_("mix")=+ve,DeltaV_("mix")=+ve C : Boiling point is smaller than expected such that vaporisation is increased D : Mixture is called azeotropic mixture Select correct facts

Answer the question (given below) which are based on the following diagra. Consider some facts about the above phase diagram : Vapour pressure diagram for real solutions of two liquids A and B that exhibit a positive deviation from Raoult's law. The vapour pressure of both A and B are greater than predicted by Raoult's law. The dashed lines lines represented the plots for ideal solutions. Total vapour pressure of mixture of 1 mol of volatile component A(P_(A)^(@)=100 mmHg) and 3 mol of volatile component B(P_(B)^(@)=60 mmHg) is 75 mm . For such case:
